Definitions

  • This application relates generally to barrier fabrics and, more specifically, to coated barrier fabrics for use in reusable medical products.
  • Barrier fabrics are generically characterized as being resistant to penetration by liquids. Because of this property, barrier fabrics are especially suited for use in the medical field to prevent or control the spread of infectious microorganisms, such as viruses and bacteria found in blood, and other potentially infectious material (“OPIM”) associated with, for example, surgical procedures.
  • OPIM potentially infectious material
  • Barrier fabric properties are critical for medical products such as surgical drapes that are used to maintain sterile surgical or procedure fields and protective apparel such as surgical or isolation gowns. Particularly where there is a possibility of coming into contact with bodily fluids, every effort is made to protect the health professional and the patient. Health professionals routinely use medical barrier fabrics during surgery, the drawing of blood, or while working with specimens containing contaminated fluids to both protect themselves and to avoid cross or secondary contamination of subsequent patients through the inadvertent transmission of infectious materials.
  • reusable medical gowns, surgical drapes, and other non-disposable medical barrier fabric products have requirements that distinguish them from other products or garments that incorporate barrier fabrics.
  • a reusable surgical gown for example, must be washed, dried, and sterilized for subsequent reuse. These procedures often involve harsh detergents and high temperatures which can quickly degrade the barrier properties of the gown and limit the number of times the gown can be reused.
  • a typical, institutional laundering/autoclaving cycle for such reusable medical products generally comprise one or more initial flushes in which the products are soaked in water at 90°-100° F for two to five minutes. Following the one or more flushes, the products are soaked in an alkali bath at approximately 120°-160° F for three to ten minutes to loosen dirt. Next the products are placed in a detergent bath at approximately 160° F for approximately five to ten minutes. This is followed by one or more rinsings at temperatures that may be progressively reduced from about 140° F to ambient temperature. The products are mechanically agitated in some, if not all of these baths. Also, following each bath, there is a drain to minimize the liquid carried over to the succeeding process.
  • an acid sour bath in which the pH is adjusted to the 4.0 to 7.0 range, and in which a softening agent may also be employed.
  • the products are extracted (spin or hydraulic press) to remove as much water as possible prior to drying.
  • the products are then dried in a tumbling dryer at an average temperature of 160° F. Typical drying times for products are in the order of 15 to 30 minutes. It is to be noted that there can be hot spots in such dryers, which can subject the products to temperatures in excess of 400° F.
  • the products are placed in an autoclave and sterilized by pressurized steam at a temperature of approximately 270° F for at least four minutes in a commercially available pre-vacuum steam sterilizer. Parameters for sterilization will differ for a gravity steam sterilizer.
  • barrier fabrics intended for use in normal (e.g., non-medical) garments, such as foul weather gear, become unusable after a single, or relatively few, institutional laundering/autoclaving cycles.
  • the fabric should be able to sustain said barrier properties after at least 10 institutional laundering/autoclaving cycles without sacrificing the comfort or the feel of the fabric.
  • the present invention relates generally to barrier fabrics and, more specifically, to coated barrier fabrics for use in reusable medical products.
  • a coated barrier fabric in one embodiment, includes a first ply and a second ply each comprising a coated side and a non-coated side, wherein the first ply and the second ply are peripherally joined together to form the barrier fabric, wherein the coated side of the first ply and the coated side of the second ply face each other and define an interior of the barrier fabric, with each coated side able to come into direct contact with one another but remain movable thereagainst and able to form a gap therebetween, and wherein the non-coated side of the first ply and the non-coated side of the second ply face opposing directions and define an exterior of the barrier fabric.
  • a reusable medical product in another embodiment, includes a two-ply barrier fabric having a first ply and a second ply each comprising a coated side and a non-coated side, wherein the first ply and the second ply are peripherally joined together to form the barrier fabric, wherein the coated side of the first ply and the coated side of the second ply face each other and define an interior of the barrier fabric, with each coated side able to come into direct contact with one another but remain movable thereagainst and able to form a gap therebetween, and wherein the non-coated side of the first ply and the non-coated side of the second ply face opposing directions and define an exterior of the barrier fabric.
  • the reusable medical product can be a surgical gown, isolation gown, or surgical drape.
  • the two-ply coated barrier fabric is provided within a critical zone(s) of the reusable medical product.
  • a method for making a two-ply barrier fabric for use in a reusable medical product includes applying, via a single pass, a non-fluorine containing polymer coating to a side of each of two separate plies of a woven or knitted fabric, wherein the coating is applied at a rate of from 1 g/m 2 to 75 g/m 2 .
  • the coating on the fabric is cured, by a single cure process and then the coated first ply and second ply are peripherally joining together to form the barrier fabric, wherein the coated side of the first ply and the coated side of the second ply face each other and define an interior of the barrier fabric, with each coated side able to come into direct contact with one another but remain movable thereagainst and able to form a gap therebetween, wherein the non-coated side of the first ply and the non-coated side of the second ply face opposing directions and define an exterior of the barrier fabric, and wherein the barrier fabric is suitable for use within or as a reusable medical product.
  • the polymer coating is silicon and applied at a rate of from 10 g/m 2 to 50 g/m 2 .
  • the content of the first and second ply comprise at least 25% polyester or at least 25% polyamide.
  • FIGS. 1 through 3B show a reusable surgical gown 10, or portions thereof, in accordance with an embodiment of the present invention. At least some portions of the gown 10, are fabricated from a coated, two-ply barrier fabric 12.
  • the fabric 12 offers a reliably durable and effective liquid barrier without sacrificing comfort or feel (as known coated or laminated barrier fabrics in the art do) due to the fabric's 12 coated two-ply construction.

  • a critical zone 11 is an area of a medical product, such as a gown or drape, where the product is most likely to come into direct contact with potentially infectious material.
  • AAMI Association for the Advancement of Medical Instrumentation
  • the critical zone 11 of a surgical gown, such as the gown 10 depicted in FIG. 1 are, at minimum, the front of the gown from chest to knees and the sleeves of the gown from the cuff to above the elbow.
  • the fabric 12 may be alternatively embodied in other reusable medical products such as a surgical drape, stand or table covers, wrappers, or other protective apparel.
  • the AAMI PB70 Standard dictates that the critical zones 11 are the entire gown, including the seams, but excluding the cuffs, hems, and bindings.
  • the critical zone 11 can be defined as the area of the drape generally surrounding the fenestration.
  • the critical zones 11 of embodiments e.g ., gowns, drapes, etc.
  • the fabric 12 may be used in other embodiments (besides in the critical zones 11 of gowns and drapes). In this way, the fabric 12 is not limited in use to any specific reusable medical product.

  • the content of the yarn that makes up the fabric 12 is up to 100% filament polyester or polyamide.
  • Polyester or polyamide such as nylon, may be chosen due to their material properties (e.g ., lint generation performance, colorfastness, inherent hydrophobicity, etc.), wide availability, and cost. It is to be understood that other non-linting polymers or fibers could be used.
  • the figures show a cross-sectional portion in a critical zone 11 of an embodiment of the gown 10. More specifically, the figures show the coated, two-ply barrier fabric 12 from which the selected portion of the gown 10 is constructed.
  • the fabric 12 is comprised of two plies 44 and 46, i.e ., a first ply 44 of woven material and a second ply 46 of woven material with each ply having a coating 42 thereon. Together, the two plies 44, 46 define an interior 48 of the fabric 12 and an exterior 50 of the fabric 12.
  • the interior 48 of the fabric 12 is the region between the first ply 44 and the second ply 46 that is generally shielded from the surrounding environment by virtue of the two-ply construction of the fabric 12.
  • the exterior 50 of the fabric 12 is the region on opposing sides of the first and second plies 44, 46 that is exposed to the surrounding environment.
  • each of the first and second plies 44, 46 is coated with a coating 42.
  • only one of the two plies 44, 46 may feature a coating 42 on one side of a ply.
  • one side of the first ply 44 is coated with a coating 42 and one side of the second ply 46 is coated with a coating 42.
  • the coated side of the first ply 44 and the coated side of the second ply 46 face each other in the interior 48 of the fabric 12.
  • the coating 42 on the first and second plies 44, 46 is not exposed to the environment. Instead, the coating 42 on the first and second plies 44, 46 is interiorly protected.
  • Such a construction offers substantial advantages over other barrier fabrics known in the art.
  • This coating-to-coating orientation diminishes abrasion to the coating material and extends product service life.
  • the useful life of the gown 10 (or other garment, drape, etc. the fabric 12 is used in) can be extended because the coating 42 is not exposed to outside or external elements, such as during the laundering/autoclave cycle, that typically lead to degradation of the coating 42 (and thus the loss of the "barrier" properties of the fabric).
  • the comfort and feel of the gown 10 (or other garment, drape, etc.) embodying the fabric 12 are improved as each or either ply of the product may have a coating weight that is lighter than has historically been the case.
  • a wearer of the gown 10 is exposed to the non-coated (e.g ., woven, knitted, etc.) sides of the fabric 12-thereby eliminating direct contact with the coating 42 materials by the wearer or user of a finished product (as in the case of some known reusable barrier fabrics).
  • the wearer of the gown 10 is exposed only to a non-coated side(s) of the fabric 12.
  • wearers disfavor the feeling of the coating 42 against their skin, especially for long periods of time (as can be the case with gowns 10 and other surgical or medical apparel in medical or surgical applications).
  • the fabric 12 as embodied in the gown 10 offers improved comfort and feel over other barrier fabrics known in the art.
  • the material for the coating 42 can be applied to one side of each of the first and second plies 44, 46 via conventional coating technologies to impart a solid, semisolid, liquid, or vaporized (e.g ., sublimation) chemistry to coat one side of the fabric 12, as is known in the industry.
  • the coating 42 may be applied to the fabric 12 using a knife coat, spray coat, foam coat, or similar methodology. It will be understood that alternative methodologies, as generally known in the art, besides those specifically listed can be used to apply the coating 42 to one side of each of the first and second plies 44, 46 of the fabric 12.
  • the material for the coating 42 can interact with the surface of the ply 44, 46 in any number of ways, as would be understood in the industry, to provide the coating 42.
  • the applied coating material can adhere to the surface of the ply 44, 46, and may form a layer thereover, such as by binding to surface fibers ( e.g., via covalent and/or non-covalent bonds, etc.) or the coating material can become entrapped within the fibers of the ply 44, 46.
  • a combination of some of all of polymerization, bonding, and physical entrapment can be used to adhere the coating 42 to the plies 44, 46.
  • the coating 42 when applying the coating 42, it is desirable to limit the penetration of the coating 42 through the ply 44, 46. It is known in the industry that applying a coating to a side of one ply 44, 46 can result in an undesirable "bleed-through" effect in which the applied coating may penetrate therethrough and appear on the other side of the ply 44, 46. It will be understood that the term 'coated' as used herein excludes the bleed-through of the coating 42. It will also be understood that the term 'non-coated' is inclusive of the bleed-through of coating 42 material.
  • a coating 42 is applied to one side of a ply 44, 46, then the side of the ply 44, 46 that the coating 42 was applied to would be considered 'coated'; however, the opposing side of the ply 44, 46, to which a coating 42 was not applied, could be considered 'non-coated', even if it exhibits bleed through effects from the coating 42 on the opposing side of the ply 44, 46.
  • the coating 42 can be applied to the fabric in a single pass and dried or cured thereon.
  • the coating 42 can be applied in a single pass and single cure application.
  • the coating 42 may be heated, as is known in the art, to desirably cure the applied coating 42 on each ply 44, 46, where cure time and temperature, for example, may be generally dependent upon the selected coating material.
  • a single pass and single cure application of the coating 42 offers distinct advantages over a two (or more) pass and two (or more) cure application, as may be used with barrier fabrics known in the art. Specifically, a single pass and cure operation desirably provides cost and efficiency benefits over an application that requires additional passes and time for curing.
  • the coating 42 can be applied to one side of the first or second ply 44, 46 in a single pass. This reduces production time and thereby reduces the cost of producing the coated fabric 12.
  • the coated fabric 12 can be cured in a single curing process as opposed to two (or more) cures-at least one for each application pass. This also reduces production time and thereby reduces the cost of producing the coated fabric 12.
  • Such benefits translate to the ability to produce more coated fabrics 12 in a shorter amount of time without sacrificing the quality of the coating 42.
  • the overall cost and the per use cost of the fabric 12 are reduced, making reusable medical products embodying the fabric 12 attractive alternatives to disposable barrier fabrics or other reusable barrier fabrics known in the art.
  • the coating 42 When the coating 42 is applied to a ply (first or second ply 44, 46 of the fabric 12), the coating 42 can be applied at a rate of from 1 grams per square meter ("g/m 2 ") to 75 g/m 2 . More specifically, in one embodiment, the coating 42 can be applied at a rate of from 10 g/m 2 to 65 g/m 2 . In another embodiment, the coating 42 can be applied at a rate of from 15 g/m 2 to 50 g/m 2 . In another embodiment, the coating 42 can be applied at a rate of from 15 g/m 2 to 35 g/m 2 . In a further embodiment, the coating 42 can be applied at a rate of from 20 g/m 2 to 30 g/m 2 .
  • the coating 42 can be applied at a rate of approximately 1, 2, 5, 10, 15, 20, or 25 g/m 2 .
  • the total, cumulative weight of the coating 42 across both the first ply 44 and second ply 46, combined can be 100 g/m 2 or less.
  • the total, cumulative weight of the coating 42 across both the first ply 44 and second ply 46, combined can be 75 g/m 2 or less.
  • the total, cumulative weight of the coating 42 across both the first ply 44 and second ply 46, combined can be 50 g/m 2 or less.
  • the coating 42 on the first and second plies 44, 46 may be 20 g/m 2 each-for a total of 40 g/m 2 across both plies 44, 46, and performed in a single pass.
  • the coating rate on each ply 44, 46 may vary.
  • the coating 42 on the first ply 44 may be 20 g/m 2 and the coating 42 on the second ply 46 may be 25 g/m 2 -for a total of 45 g/m 2 across both plies 44, 46, and performed in a single pass.
  • plies 44, 46 of the fabric 12 results in plies 44, 46 with a desirable comfort and feel.
  • Some known coated fabrics used in reusable medical products feature thick coatings. As such, these fabrics have an unpleasant rubber-like feel.
  • medical apparel made from such thickly coated fabrics are uncomfortable to wear, especially for long durations of time (such as during a medical procedure).
  • applying a light coating 42 on the first and second plies 44, 46 results in a finished fabric 12 that is similar in feel and comfort to an uncoated fabric, but with the desirable barrier properties of a coated fabric 12. As such, the fabric 12 achieves the desirable properties of a reusable barrier fabric without sacrificing on comfort or feel.
  • the coating 42 can be a fluorine free coating.
  • Other known coated barrier fabrics often utilize chemical hydrophobic finishes containing fluorocarbons, such coatings are known to diminish in effectiveness through repeated processing and use cycles.
  • the material for the coating 42 in one example, may be selected from any of a variety of non-fluorine containing materials.
  • the coating may be selected from any of a variety of non-fluorine containing polymers such as acrylic, polyurethane, thermoplastic polyurethane, silicone, or other similar materials.
  • the coating 42 may be composed of any combination or mixture of the above non-fluorine containing polymers. In one example, the coating is silicone.
  • the coating 42 may be selected based on a desired coefficient of friction, such that the coated and facing surfaces of the plies 44, 46 can move freely thereagainst and with little to no damage thereto.
  • FIG. 3A the figure shows the coated, two-ply barrier fabric 12 from which the selected portion of the gown 10 is constructed with a gap 52 between the first ply 44 and the second ply 46 of the fabric 12.
  • the gap 52 is not necessarily to scale in the figure.
  • the presence of the gap 52 in the interior 48 of the fabric 12 signifies that the first ply 44 and second ply 46 are not adhered or bonded to each other in this embodiment.
  • the first ply 44 and the second ply 46 still are joined about their peripheries by techniques known in the art, such as by sewing.
  • the plies 44, 46 are not otherwise constrained with respect to each other. Specifically, the first ply 44 and the second ply 46 are free to move against each other in the interior 48 of the fabric 12. Accordingly, there are no additional plies or layers situated between the first and second plies 44, 46.
  • Coatings 42 are generally abraded and/or degraded when they come into contact with any number of environmental factors. For example, if the coated side of the ply were on the exterior 50 of the fabric 12 as opposed to the interior 48, then the coating 42 would be exposed during the institutional laundering/autoclave cycle where the coating 42 could be damaged by the harsh detergents, agitation during a washing phase, or heat during a drying phase. Such abuse could severely diminish the useful life of the fabric 12 as a barrier fabric by degrading the coating 42.
  • the coated sides of each of the plies 44, 46 face the interior of the fabric 12, and each other. It is understood that the coating 42 is generally not abrasive or generally substantially detrimental to itself. As such, when the coated side of the first ply 44 and the coated side of the second ply 46 rubs or moves against each other in the interior 48 of the fabric 12, the contact should be generally non-abrasive or non-degrading, i.e ., generally non-detrimental. That is to say that, in general, the coated sides of the plies 44, 46 are free to interact with each other without worry of detrimentally damaging the coatings 42 during the useful laundering life of the gown 10. In this way, the construction of the fabric 12 (e.g.
  • FIG. 3B the figure shows a cross-section of a portion of an embodiment of the gown 10, and more specifically and in contrast to FIG. 3A , the figure shows the coated, two-ply barrier fabric 12 from which the selected portion of the gown 10 is constructed with no gap 52 between the first ply 44 and the second ply 46 of the fabric 12.
  • the plies 44, 46 are not adhered or bonded together. But rather, the plies 44, 46 are free to move against each other ( e.g ., in the transverse direction).

  • the two-ply construction of the fabric 12 offers advantages of other reusable barrier fabrics known in the art.
  • the fabric 12 offers redundancy in the form of two plies 44, 46 that each comprise a coated side.
  • the redundancy of having each of the two plies 44, 46 coated on one side provides for a more reliable fabric 12 with a longer useful life than other coated barrier fabrics known in the art. Further to that end, it is a feature of the fabric 12 to exhibit excellent barrier fabric properties.
  • the two-ply configuration of the fabric 12 results in a higher hydrostatic resistance than either of the two plies 44, 46 would yield individually or would be yielded by a single ply that was coated with a thicker coating 42.
